Ansible stores the hosts it can potentially operate on in an inventory file. The syntax is one host per line. Groups headers are allowed and are included on their own line, enclosed in square brackets that start the line.

Ranges of hosts are also supported. For more information and additional options, see the documentation on http://docs.ansible.com/.

Extensive documentation is available in the documentation site: http://docs.ansible.com. IRC and mailing list info can be found in file CONTRIBUTING.md, available in: https://github.com/ansible/ansible
